"Distinguished professors, I would like to show an important Russian guest the power of German science and technology, and the beauty of German science, and conquer them with force and beauty, and this conquest should be carried out in a vivid and interesting way, so as to arouse the exuberant purchasing power of this Russian guest!"

Joey looked up at the German lights in front of him and said solemnly, "Let the Russians willingly pay for Germany's technological conquest with gold and precious stones!" ”

"Jojo, the power plant of the Siemens gentlemen is advancing, show them our thermal power plant?" Professor Kirchhoff asked not too sure.

"Professor Kirchhoff, the thermal power plant is so big, my idea is to be small, to be relevant to our daily lives, I don't want to make it too big, after all, I just invite this Russian guest." Joey spoke his mind.

"Qiaoqiao, does it have to do with daily life, if you are preparing a dinner party, I recommend electric lights, how about it?" Professor Helmholtz had a good idea of Joey's thoughts.

"Professor Helmholtz, the electric light is so good, is there anything other than the electric light, such as an appliance that can be used at home?" Joey continued to ask.

"How's the electric fan?" Professor Kirchhoff chimed in, "When I was working with Siemens to improve the technology of electric motors, one of my American students, because he felt the weather was hot, had the whim to change the fan that was originally driven by a mechanical mainspring to a fan driven by an electric motor. If you're going to use electricity for your dinner party, I think it's a pleasure to have a motor-driven fan on a hot summer day. ”

"Electric fan?!" Joey grinned, "Okay, Professor Kirchhoff, wait I want to meet your students. Professor Kirchhoff nodded in agreement

"Getting a cool temperature in the summer is essentially a heat exchange, Rudolph, your research paper on the mechanism of heat exchange in ammonia compression is impressive, can you make a refrigeration device based on this?" Professor Helmholtz asked Professor Clausius.

"Mr. Professor Helmholtz, let me think about your proposal." Professor Clausius pondered silently for a moment, then said, "Yes, but the power to drive the ammonia compression device is a problem. ”

"Rudolph, how about solving it with a motor?" Professor Kirchhoff chimed in.

Professor Kirchhoff's words inspired Professor Clausius, and the luck of inspiration came, and no one could stop it, and then Joey's words also brought good luck to Professor Clausius.

"Mr. Clausius, in the past few days, if it is convenient for you, I would like to introduce you to an inventor, Professor Carl Paul Gottfried Linde from the Technical University of Munich, Professor Linde has been working on the invention of the field of air refrigeration, maybe you will have new breakthroughs." Joey suddenly remembered Professor Lind and hurriedly introduced him to Professor Clausius.

"Jojo, I'm at the University of Berlin this week, and as long as it's someone you introduced, I want to meet it." Professor Clausius smiled and agreed.

Just as Joy was getting Professor Clausius's permission, Professor Maher also thought of a useful invention for Joy, and pointed out to Joy, "Jojo, I suggest you go and see Mr. Ernst Siemens as soon as possible, Mr. Ernst Siemens has just recruited a German-American engineer from the United States named Emil Belliner. ”

"I was invited yesterday by Mr. Ernst Siemens to meet Mr. Bellina at Siemens, and he had a very interesting invention, unlike the drum phonograph of the Frenchmen Lyon-Scott-Martinville and Charles Crow, Mr. Belliner's is discography."

"And Monsieur Bellina gave his invention a very German name, to distinguish it from the French invention, as if it were called...."Professor Mach thought carefully for a moment, and a word popped out of his mouth: "Gramophone, yes!" That's it! ”

"Gramophone, Mr. Bellina, record phonograph?!" These three words, in the heart of Joey, who had loved music in his previous life, eventually became only one word: "Grammy, Grammy!" ”

Grammy, Joey's previous life, the highest award in the American recording industry and the world music industry, the famous gramophone-shaped trophy is modeled after the record phonograph invented by Mr. Belliner.

"Jojo, if you can put that thing on the dance party at the dinner party, it will definitely surprise everyone, including your Russian guests, and to be honest, if Siemens puts this product on the market, I'll buy it too." Professor Maher said sincerely.

Joey hugged Professor Maher hard, the smile on his face could flow out, and he asked excitedly, "Mr. Professor, how do you know so clearly?!" ”

Professor Maher was a little at a loss, so he could only let Joey hold him, and said with a smile, "Mr. Belliner's gramophone still has some minor acoustic defects, I helped him solve it, and now the sound flowing out of this gramophone is very beautiful, like someone singing around you!" ”

Professor Mach was glad that he had found a useful invention for Joey.

Suddenly, a young voice sounded next to him, "Joe... Joey, if your dinner party is a gathering of young people who love music, I would like to recommend the Schumer brothers to you. Although he was one of Professor Helmholtz's favorite disciples, in the face of many seniors in the German scientific community, Dr. Hertz was obviously not as open as the heartless Joey.

"Hi, Mr. Hertz! What did the Schumer brothers invent? In line with the mentality that if you can be contaminated with more genius, you can be contaminated with more, and Joey has always started with hugs for young German geniuses.

Dr. Hertz had seen Joey a few times since April, so he was quite acceptable to Joey's behavior of rubbing genius oil, and said with a smile, "Brother Schumer, they don't like people to call them inventors, they like people to call them players." ”

"Player?!" Joey repeated the familiar word and smiled.

"yes, I don't know why their brother likes to call himself a player, what a strange name." Dr. Hertz laughed too, "But they play something fun, it's called a player piano." ”

"Use the perforated paper roll as an air valve, let the wind of the bellows pass through the holes on the perforated paper roll, drive the wooden fingers connected to the machine, and the wooden fingers strike the keys of the piano, and there is a group of violins on the top of the piano, which also uses the wind to drive the holes on the perforated paper roll, and rotates the strings with machinery."

"I've heard this player piano play on the Schumer brothers, the violin sonatas of Mozart, Schubert, Beethoven, Brahms, Strauss, and even the most famous of all now, Debussy's violin sonatas in G minor, which is simply wonderful!" Thinking back to the music he had heard, Dr. Hertz had a strong aftertaste on his face.

Joey did not hesitate to get to the address of the Schimmer brothers in Berlin, and such a talented "player", Joey would never give up.

"Automatic piano and record phonograph, haha, the entertainment overlord of this era is in its infancy, let Mr. Siemens sell the machine, I can fill records and set up a record company."

"Is it the pride of the German entertainment industry now, BMG Bertelsmann Entertainment Group, or is it called the American name Time Warner?! Or call it BMG in Europe and Time Warner ...... in the United States, it's a real headache, no matter what, register the name first! "Joey is slipping further and further down the road of maliciously squatting on famous brands.

Now with the new entertainment tools provided by Professor Maher and Dr. Hertz, Joey is thinking about it again.

"In the heat of summer, the refrigeration equipment that produces coolness during the day falls on Professors Clausius and Lind, and at night the lights are the electric lights of Mr. Simon, the electric fans of Professor Kirchhoff's students, and the gramophone of Mr. Belliner.... That's not enough, I'm going to find some more interesting projects. ”

The rest of Professor Willer, Professor Weber, Professor Bunsen, and Professor Negri saw Joey's inquiring eyes, and everyone looked at each other and smiled bitterly, and finally Professor Willer, with his oldest age and recent acquaintance with Joey, had no choice but to lean on the old man and said, "Jojo, go find Professor Beyer and ask them, we will talk to Professor Clausius about the details of this grand event." ”

After driving Joey away, Professor Bunsen laughed, "I haven't felt so much pressure in research for many years, and now it's really like I did academics when I was younger." ”

"The pressure gives me the feeling of being a young man full of energy." Professor Weller also laughed and said, "I like the way this little guy puts pressure on you, and cares for you in every way, so that you feel sorry for this care if you don't put in 200 percent of your effort." ”

Hearing what the eldest Professor Weller said about Joey, everyone present smiled and nodded.

According to Professor Wheeler's instructions, Joey plunged headlong into the circle of chemistry gods, not to mention really let Joey find something interesting.

Professor Beyer's student, Dr. Hermann-Emile Louis Fischer, who has been studying alkaloids, actually recommended two amazing food additives to Joey, an extract from African coffee cherries: caffeine; and coca base, an extract from the coca leaf in the Andes Mountains of South America

Caffeine is Dr. Fischer's latest research, but cocaine was the work of German scientists Friedrich Judek and Albert Niemann more than a decade ago, and has been widely used in the medical industry as a miracle drug.

One of the most miraculous medicinal liquors of this era: Vin Mariani, a cocaine wine with a lot of cocaine, was introduced in 1863 and was appreciated by the most famous people of the time, including Pope Leo VIII., Prince Wales (later Edward VII), the stallion Prince Wells, and the tsars from Alexander II onwards.

Dr. Fischer swore to Joey that these things were absolutely needed for a youthful party, and that these things could free the mind from the shackles and shackles of the flesh......

Joy was still thrilled to hear Dr. Fischer introduce cocaine, which meant having cocaine's added syrup water, filling it with pure carbon dioxide gas, filling it into a proper glass bottle, and finally combining it with Mr. Linde's ice machine.

A bottle of Coke that clattered when opened, poured into a glass full of crystal clear ice cubes, and tasted sweet and refreshing.

Ps. The main ingredient in the early Coca-Cola contains cocaine, and now the cola is replaced by caffeine, the raw materials of Coca-Cola are not mysterious, and the formula that Coca-Cola strictly adheres to should actually be called the process formula, which is the patented formula that Coca-Cola has been keeping secret.

However, when Dr. Fischer introduced another youth body weapon, Joey couldn't help but laugh.

Dr. Fischer introduced Joey to an anesthetic commonly used by dentists: laughing gas.

Nitrous oxide gas, discovered in 1772 by Professor Joseph Priestley, a British chemist who discovered oxygen, was officially used as a medical anesthetic by American dentist Wells in 1844.

Dr. Fischer introduced the form of joy that was popular among young people in the nineteenth century. Well, no matter what era it is, young people in Europe have always dared to be the first in the world when it comes to "showing off their individuality".

Joey looked at the crowd of young doctors around Dr. Fischer, and could only shake his head helplessly.

"Well, laughing gas is never a drug in law, but you guys are also drug abuse, and it's always wrong...... Alas, I've also had the experience of drinking cough syrup in the face of study pressure, well, everyone is not good in this matter. ”

"In any case, drug abuse is always a matter of less pride, and it seems that the work of prescription drugs and over-the-counter drugs is going to be advanced...., but the mental emptiness is not something that can be solved by a law, and it is a headache ....."
